Application led .April 7, 1909. Serial No. 488,423.

To all whom fit lmay concern:

Be it known that I, I-IENRY G. VoIGH'r, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Panic-Bolts, of which the following is a full, clear, and exact description.

This invention relates to improvements in panic door bolts, particularly of the type illustrated iii my com anion applications Serial No. 480,297 and o. 447,074.

The object of the present invention is to provide an additional safety device which l relates particularly to the bolt construction.

In the accompanying drawings Figure l is a perspective view o a door, broken away and contracted and bearing on the inner face thereof my improved panic bolt.. Fig. 2 is a relativel enlarged view of the inner side of Vthe bot proper and holder or case therefor. Fig. 3 1s a section on the line w-w of Fig. 2. Flg. 4 shows a side and inner end elevation of the latch bolt, detached. Fig. 5 is a relatively enlarged view of theinner side of the lock case showing the interior mechanism. Fig. 6 is a section on the line zzz-a: looking in the direction of the arrow Fig. 5.

1 represents a door, 2 is the lock case, 3.-3 are spring-projected latch-bolts arranged in the preferred form at the upper and lower edge of the door.

4 is a bracket carried by the lock case.

` 5 is an operat'ng bar extending across the inner surface of the door and arranged to move to and from the door, said bar being Vconnected to the mechanism within the case 2 through the medium of an arm pivoted on the bracket 4.

The mechanism in lock case 2 may be of any suitable form toproject the rods 7-7, which are suitabl connected with the latchbolts 3 3, where y the latch-'bolts may be retracted by the movement of the bar 5 toward the door. One suitable form of such mechanism` is found in my companion application above referred to, but since no claim of novelty is based thereon in the present application, it is unnecessary to describe the same herein. v

' Referring now particularl to Figs. 2 to 4, it will be 'seen that the latcli-bolt 3 is pro- 'vided with one substantially square side and an opposite beveled side. lThe-square' side arranged to -encounter 'of the 4latch-bolt is intended to encounter the strike-plate (not shown) to resist the opening of the door at the proper time, Whereas the beveled side of the latch-bolt is intended to encounter said strike-plate as the door is closing, whereby said latch bolt 'is forced back in' the usual manner. The latchbolt 3 is pivoted at 9 to a frame 10 slidably mounted in the case 11. The upper end of the rod 7 is provided with .a head 12 slidable in the frame 10. The head 12 has a key 12a the tail of the latch 3.

In the particular form shown, thisy key 12 is in the form of a single projection or rib extending across the end of the head and arranged to enter a notch 3a latch 3 so as to prevent said latch from turning on its pivot 9. When the rod 7 is retracted, the key 12a is first withdrawn from the notch 3, freeing the latch 3 so that if pressure is applied to the square face of the latch bolt, as would be the case were pres-A sure applied against the inner side of the door. to which the lock is applied, the said latch-bolt would swing back into the position indicated in dotted lines, Fig; 3, instantly freeing the door. If for any reason the latch 3 should han ,continued retrction ofthe rod 7 would cause the head 12 to engage the shoulders 10?* of the slide frame 10, drawing back the latter and drawing the latch 3 bodily in the same direction. A sprin 14 of any suitable form may be provider? to cause the latch-bolt 3 to normally assume the 'osition indicated in Figs. 1 to 3. Where it 1s desired to make the case 11 very compact, as a clearance' offset 11a may be provided to permit the bolt 3 to swing back into a h orilzontal position so as to clear the door casing.

1'5 is aspring for normally advancing the latch-bolt and atcb-bolt support, sa1dspr1ng in the presentfconstruction bearingat one end against an abutment 11b within the case 11 and at the other end against the under side of the head 12. The body of the head 12 acts as a means vto retract the latch carrying frame 10, while the nose of key 12 performs a separate function and acts asf a means to lock the latch-bolt 3 against rotation uponfits support` 9. These means and 12 are preferably integrally united, al-

though obviously 'not necessarily so. Inra'f rions respects, the construction shown herein 'is susceptible-.of modification, and itshould shown in the drawings,

' Patented Nov. 2, 1909.

in the t'ail of the accomplish this, the lever 26 ed latch-bol be understood that I contemplate that the following claims cover and include sch modifications as operateto achieve the pur` poses herein pointed out.

As will be seen, the lever 8 is arranged the bolt-retractlng mechanism by a movement either toward or from the door. To

is pivoted intermediate its lengthand its two ends are oppositely engaged by horns 8"-8c on the operating lever 8. One end of the lever 26 engages with the turn is connected with a walking beam 2l pivoted at 22 and connected by links 23-`23 to the bolt stems 77.

24 is a roll-rack engaging slide 25, which latter is also connected with the walking beam` 2l in 27 is a dogging slide carrying a tumbler 28 and operated by a roll-back 29 to engage or disengage a lug 30 on the roll-back 24. By this means, the roll-back 24 may be held against operation. The operating means for the roll-back would naturally be located on the opposite side of the door from the lever 8. Since in devices of this character the object is to guarantee an\exit in case of an emergency or panic, it follows that the operating lever 8 would be arranged on the inside of the door; hence the roll-back 24 'would be arran ed for operation from the outer side of te door. The roll-back 9 may be arranged to be operated from either or bot-h sides of the door whereby the dogging slide 27 may be actuated. As will be seen, when the roll-back 24 is dogged, the apparatus may still be operated from the inside by the lever 8.

A detailed description of the parts last described will be found in my companion application first above referred to, and since no specific claim is redicated herein, a further description ofp these parts is un'- necessary. I do not claim, broadly, in this case the operative connection of the transverse bar with the lock mechanism as this forms the subject matter of my application N o. 504,472, tiled June 26, 1909, which is a division of this application.
